I say that the ball gets handed to guttersnipe even though DSJ is correct.

The variant in question deals with the circular shoulder bolt on each leg. The regular R2-D2 legs have a bolt that is smooth and flat. The R3-T7 bolt or legs have a bolt that has indentations in the circular bolt that look a little like an 'X". I do have both variants and would be happy to send you images if this isn't enough info.

Regarding the thrill of the hunt...

With hunting out new friends and making new friends, that is a very cool thing and a lot of why people trade. You can never have enough good friends and international contacts.

I have always considered the hunt to be the search for figures and collectibles. You can't go in with preconceived notions or it's not fun. The thrill of being surprised is the best element.  While we all have favorites and figures we want, it's better to walk in with a blank slate and let the figures you want find you. I guess it would be the jedi approach to hunting in a way. Let the figures find you. You just have to put yourself in the right places. Nice little Treatise and I agree with most of those listed. I do think generosity and being hopelessly honest will also get you far in the game.

I have a rule that I think is one of being fair to others.  If you are lucky enough to find more than one rare figure or collectible, leave one behind for another person. Don't hoard or be too greedy. Spread the wealth. I know some are too good to pass up, but it is an honorable thing to do. Some may say stupid, but still honorable.  

Went down the toy clearance aisles at a Walmart that hasn't seen many new SW action figures in a while and found they were clearancing all their 12" Dengars and Zuckuss Action Figures for $10 a piece!!! I could not believe my eyes! But I could believe it when I looked in my wallet and found nothing to buy them with. They were stocked though, so hope to return and find a couple of each. I encourage everyone to check their local walmart for similar clearancing prices. Too good to pass up!

Falumpaset? I think that may be a specific name for one creature and maybe not the general name of the species. That's my guess though, falumpaset.

Or it could be that it is an overall 25th Anniversary that is being extended beyond the 25th year and they will celebrate it by releasing 3 sets of these for every movie. I mean, the word 'Star wars' preceeds all of the movie titles. The Silver Anniversary is a major deal, so they may milk it for all it's worth...

Yeah, but none of it really explains anything about the process of vaporizartion. I'm just wondering if there is official justification or definition for the process. Do they focus and meditate so deeply that they actually are able to become the energy of the force and their physical being breaks apart into the individual vibrating, molecular midichlorians? or is it, "POOF!" and that's it? Once physical, now guiding consciousness. I mean, if they become one with the force, why is he (they, if Yoda is in on this) represented as a physical spirit being instead of just light and a voice? Does that reflect the western societies need to be able to see the physical? I mean, there weren't any Buddha statues until some western ass, said, I can't meditate or imagine something I have never seen. I need to know what I'm meditating on in order to do it. Was that just to utilize the visual media? How is it explained in the novel? Do they detail how Obi-Wan just vanishes? Do they detail that Obi-Wan's spirit form appears to Luke and Yoda in ESB? He's just a voice in A New Hope. Thank the Jedi he was a small spirit form sitting cross-legged on Luke's X-Wing dash board. I agree that Obi-Wan and Yoda are bad asses (Anakin too in the end) if the are able perform the oneness with the Force trick. The real question is: "How can you justify it? I just can't accept it as "it just happens". I am now completely obsessed with this and will stop my blithering.
